TL;DR: Measurements of nuclear activation cross sections from carbon can be used for proton fluence calculation in proton therapy by measurements of the activity after irradiation by measuring the cross sections after gamma-ray spectrometry measurements.

Improvements to the muon veto of the Dortmund Low Background Facility.
TL;DR: The Dortmund Low Background Facility is a germanium gamma-ray spectrometry laboratory situated above ground with a background level comparable to laboratories situated underground, due to the recent completion of the muon veto.

TL;DR: The first studies show the potential of titanium for proton beam range verification, which requires a precise knowledge of the produced radionuclides from titanium after the irradiation with protons and the corresponding activation cross sections.

TL;DR: In the experiments of the current study, cylindrical, thick brass targets were irradiated with quasi-monoenergetic proton fields and 62Cu was the most important detected residual nucleus regardless if specific activity or equivalent dose is considered.
